Person still in fossle land found.
Presumably you were referring to fossils?
Seems a bit odd, coming from someone that seemingly cannot adapt to one pedal driving, which is clearly the way all EVs are going, so much so that the lack of it in any new model would be enough to stop me buying it.
I would hazard a guess that you have some connection with aviation, so presumably you're very much aware of the challenges in making an intuitive and foolproof HMI. I was a flight test scientist for a bit over 22 years, and in that job experienced everything from the seriously dire HMIs from aeroplanes designed during the 1950s and 60s, though to attempts to bring ergonomics into cockpit design in the 1970s and 1980s (not always successfully).
Car controls should be intuitive, and not require the driver to take his/her eyes off the road, that much is plain common sense. With no means of locating either the position of a touch screen control, or whether it has functioned as desired, without looking at the screen, a touch screen is clearly very much sub-optimal for any control the driver needs to use quickly and intuitively, without taking their eyes off the road.
There's a very good reason that many aircraft controls are designed so that they can be located and operated by touch alone. It improves the performance of the crew by a significant amount, and has been proven to save lives. The first time I sat in an Apache, with more than a dozen functions controlled by switches and buttons on the cyclic and collective I wasn't impressed with the design, but it turns out that the layout was pretty intuitive to use in practice. Pretty much every control that needs quick and easy access in flight is right there at a fingertip, easily identified by tactile feedback, with no need to look at anything inside the cockpit. Tesla have already provided ten potential control options on the steering wheel, without multiplexing combinations, in a similarly easy to access position, but haven't really made best use of them, IMHO.
My drive last night highlighted some of the flaws in relying solely on the touch screen. The auto wipers played up (again), just as I was trying to drive along a dark, narrow and windy lane. I had to slow almost to a stop to safely use the touch screen to switch them back to manual, as controlling the wipers is impossible without looking at the screen, both to see the buttons and to confirm that my finger had selected the right option. This latter point, the need to continue looking at the screen for some seconds to confirm an operation is the primary safety concern I have. With a tactile control, confirmation of operation is provided immediately by feel alone. There may be a need to briefly locate a control by taking eyes off the road, but there isn't a need to continue to look at the control to confirm that the desired option has been set. It would be easy enough to add manual wiper functionality to the button on the left stalk, for example. I don't think there's any other car on the road that has wiper controls on the dash any more, for good reason, it is demonstrably safer to have them easy to hand near the steering wheel.
